Changing stroke rehab and research worldwide now.Time is Brain! trillions and trillions of neurons that DIE each day because there are NO effective hyperacute therapies besides tPA(only 12% effective). I have 523 posts on hyperacute therapy, enough for researchers to spend decades proving them out. These are my personal ideas and blog on stroke rehabilitation and stroke research. Do not attempt any of these without checking with your medical provider. Unless you join me in agitating, when you need these therapies they won't be there.

What this blog is for:

My blog is not to help survivors recover, it is to have the 10 million yearly stroke survivors light fires underneath their doctors, stroke hospitals and stroke researchers to get stroke solved. 100% recovery. The stroke medical world is completely failing at that goal, they don't even have it as a goal. Shortly after getting out of the hospital and getting NO information on the process or protocols of stroke rehabilitation and recovery I started searching on the internet and found that no other survivor received useful information. This is an attempt to cover all stroke rehabilitation information that should be readily available to survivors so they can talk with informed knowledge to their medical staff. It lays out what needs to be done to get stroke survivors closer to 100% recovery. It's quite disgusting that this information is not available from every stroke association and doctors group.

Researchers create "xenobot" – world’s first living, self-healing robots created from frog stem cells

With any brains at all in the stroke world this would immediately be seen as useful in delivering interventions for stroke. But we have NO BRAINS IN STROKE.  So nothing will happen.

Researchers create "xenobot" – world’s first living, self-healing robots created from frog stem cells

The thought of microscopic robots brings the image of Hollywood blockbusters such as “Terminator” and other science-fiction movies to mind that are set years into the distant future. But a group of scientists have gotten one step closer to bringing these elements only seen on the big screen to reality.
Researchers at the University of Vermont and Tufts University were able to create what they call “xenobots” – the world’s first living, self healing robots created from frog stem cells. Named after the African clawed frog, Xenopus laevis, they are tiny blobs of moving cells made from stem cells obtained from frog embryos. They are less than a millimeter wide, making them small enough to travel inside the human body. Additionally, they have the ability to walk and swim, survive for weeks without food, and work together in groups.
Here is a brief video showing what these cells look like under the microscope:
The researchers were able take the stem cells from the embryo and increased their numbers by incubating them. After this, the cells were cut and rejoined using tiny forceps under a microscope into specific forms designed by artificial intelligence. These newly created forms are ones not found in nature and what is more remarkable is that they started working together. The skin cells bonded to form a structure while the heart cells worked together to create motion. These cells also displayed the ability to heal themselves after being cut.
In a news release from the University of Vermont, Dr. Josh Bongard, who co-led this research, described the xenobots in more detail.
“These are novel living machines. They’re neither a traditional robot nor a known species of animal. It’s a new class of artifact: a living, programmable organism.”
In the same news release, Dr. Michael Levin, who also co-led this research, talks about the possibilities these xenobots have for real world applications for a wide range of issues.
“We can imagine many useful applications of these living robots that other machines can’t do, like searching out nasty compounds or radioactive contamination, gathering microplastic in the oceans, traveling in arteries to scrape out plaque.”
The full results to this study was published in the Proceedings of the National Academy of Sciences (PNAS).

Artificial Intelligence methods automatically design diverse candidate lifeforms in simulation (top row) to perform some desired function, and transferable designs are then created using a cell-based construction toolkit to realize living systems (bottom row) with the predicted behaviors.
